Friend has a big problem with his P pickups...

I have a friend who own a Fender Mark Hoppus bass and every time i see him live i can't help but notice something,every time he plucks the strings a bit harder with his pick,the bass produces a loud 'click' noise and the note he was playing is silenced(completely overshadowed by the loud click).What could be the problem? (his bass is brand new)

My bass has been making a sound occasionally that I'm having trouble detecting. It's none of the above. Could be a fret related noise but it's pretty rare and I'm usually fairly familiar with those kind of noises.
It's kind of a med volume click. I'm wondering if it's bridge related at all. Only happens with the e string. Any ever have any bridge noises? Maybe something is a little loose, saddle moving or something. Guess pulling off the string and checking the bridge would be the way to go.

What's this "tuned to pitch" nonsense? Sounds like witchcraft to me. I like em real loose like in that ZZtop video where they faked a headless pair by cutting the heads off cheapie necks, and used a capo to barely hold strings on. That's the feel I go for. Uberslinky

I had a P pickup where one side would click if your finger hit the pole piece. Apparently the pole pieces weren't grounded on that coil of the pickup. A lot of times they will ground them with adhesive foil and it can come unstuck. My solution? Replace the pickups and electronics. Extreme? Yep.
